I've tried this and it works quite well on SCO UNIX and SCO XENIX. I'm now feeding
someone a news feed over a double PPP link. Looks something like:

	SCO UNIX <-> router <-> router <-> router <-> SCO XENIX
                             ^          ^
                             |          |
			     PPP        PPP

The outside lines are ethernet. The inside two links are PPP running over a V.32bis
/V.42bis and V.32 connection respectively.

The problem now is that with SCO's uucico you can only use the "g" packet level
protocol. This is blessed with small packets (64 bytes data) and a small window size
(3, can be adb'd up to 7). The end result is truly amazing throughput :-) About 102
cps with windowsize of 3 and 170 with windowsize 7.

Anyone feel like building uucp spoofing into uucpm and uucpd :-) (aka Trailblazer
uucp spoofing). 

I also heard a rumour that a uucp replacement was announced at a Dallas BOF, any
details? A replacement uucico would certainly do the trick.

Anyway we now get to knock SCO (and other 386 vendors) for not including a uucp daemon
when we can see how easy it is to implement AND for being so totally short sighted 
that they didn't include any protocols other than the standard "g" protocol. It's
one thing to not port something (like uucp[md]) but presumably they actually had to
turn off linking in the alternate protocols.

I dream of a day when van-bc has all the networking facilities available on a Sun. 

Maybe I should start looking for a Sparc Clone. Might be the only way to get
proper networking. I sometimes wonder if the Intel UNIX market will survive the
attack of the Killer Micros (as embodied by various RISC UNIX systems).
